Colors drop- similar to convergence problem

I had the convergence fixed two years ago and thought that was the same problem here. The repair person says the DCU has failed and needs to take in to the shop. Est cost $500 - $700I am wondering if I am just throwing money out the door at this point or if this is a typical age related problem.

No i think he is taking u for a ride. u just need convergence ic and what happins is sometimes tv service centers will use sup replacemeet parts in stead of original parts u need to replace the convergenc ic whit original parts.and if they donot put heat grease on the convergence ics and that is y they go out again. but i have never seen the digital convergance unit go bad. and this problem can be repaird in your home for 200. - 250.oo at the most marty

yes all u have to do is put the ic number witch may be a stk4274 and the web will find the part for u.if not give me the number and i will tell u where to get it martyyes all u have to do is put the ic number witch may be a stk4274 and the web will find the part for u.if not give me the number and i will tell u where to get it marty

The tv have a problems known as a convergence pictures problems,it is dead.Tv have any colors lines like R,G,B mis alignments,also tv have any colors shaded shadows pictures or a 3D pictures look alike?Yes,than the tv have a convergence board problems and it is dead to causes all of these problems.The tv convergence board must have to repair like replacing 2 STK convergence ICS and some or all of it resistors too.To fixed the tv convergence board to solved the tv convergence pictures problems.The tvs shops repair a DLP tv convergence board will cost u like $300-$350 for parts an labors.

I had similar symptoms about a year ago. Also came on sudden. The red convergence chip had burned out (poor heat sinking on this model Hitachi). Replacing the color convergence chips fixed it. ($50 for parts.) First, however, have you tried the "magic focus" function? That's explained in the manual, which is available online IIRC, but I'd have to look for the link if you need it.

Projection TV sets need to have all three colors - RED - BLUE - GREEN - lined up correctly on the screen in order for the video to look normal. When its out of alignment the video will look 3D, wavy, distorted, etc. Most of the time you just need to adjust your convergence in the TV menu. If you cannot adjust it in the menu - then your convergence is broken and needs to be repaired.

Convergence problems are very common on all Projection TV sets including Sony, Samsung, JVC, Philip Magnavox, Panasonic, Akai, Pioneer, Hitachi, Zenith, and others. You can get a convergenece repair kit from the link below.

Using your original remote go-to the settings menu then goto the convergence section.

Try to adjust the red and then the blue convergence.

You should be able to move RED and BLUE in all directions - up, down, left, and right.

If you can't move them in all directions or cant move them far enough your convergence chips are bad and should be replaced. This is a common problem.

Note: If you TV has as flash focus or magic focus button only try pressing the button. If it fails to fix the convergence your need to fix it. See below for a solution

CONVERGENCE SOLUTION

You will need to replace the convergence chips and possibly some convergence resistors and pico fuses. This is a a fairly easy DIY job if you know what you are doing. If you have never done this before we would advise calling a shop or if you want to do it yourself get a complete kit with instructions and support from www.TvRepairKits.com

IF THE SCREEN IS ALL RED WITH VIDEO VISIBLE AND RETRACE LINES. ADJUST SCREEN CONTROL IN THE FRONT FOR THE RED TUBE ONLY. TURN CONTROL COUNTER CLOCKWISE. IF THAT DOESNT DO IT THE TUBE CAN BE REJUVINATED.

I dont think this problem can be fixed without solder work or part replacement of convergence section. Its no just matter of fuse. You should get repair facility from concern service center because TV has dangrous voltages inside and qualified person knows how to deal with TV.

First off, you do need the original remote to adjust the convergence, Second, the service mode will not fix your problem. If the colors have all drifted, you have a problem in the convergence drive circuit. Most likely the convergence IC's are bad or going bad. The service menu is not a fix all for the problems with the convergence. The service mode will or can make minor convergence adjustments,not anything where all the colors are off. If you have no solid state repair experience, call out a service person to assist you in this repair. Good Luck
